The grand complication with the self-propelled escapement carriage is a perennial obsession of watch enthusiasts. Brands as varied as Hong Kong's Memorigin and Geneva's Patek Philippe have offered tourbillon watches at prices ranging from hundreds to millions of dollars. But does the tourbillon itself render a watch more accurate than its conventional Swiss lever equivalent at any given price level? Tim explains that the very best tourbillon wristwatches from Jaeger-LeCoultre, Greubel-Forsey, and Louis Monet do live up to the legend this Abraham-Louis Breguet innovation, but most tourbillon watches cannot achieve better precision than even well-regulated ETA calibers such as the 2824 or 2892. In fact, a Tissot-entered ETA caliber has rivaled the best tourbillon watches in the bi-annual Concours de Chronometric at the Museum of Horology in Le Locle, Switzerland. As a device designed to operate in the typical "fixed" position of pocket watch, the tourbillon doesn't always achieve better timing precision in a wrist watch format. For that reason, Watchuwant rates this rumor FALSE. Video and content by Tim Mosso and Pheline Jerome.
